4 Claims.

This invention relates to rubber shoes and has for its object theproduction of a shoe which may be extended lengthwise to fit'variouslengths of leather shoes on which said rubber shoes are worn.

Another object of the invention is the provision of means whereby thefore part of the rubber shoe may be adapted to fit various widths ofsaid leather shoes.

These objects are attained by the construction of the rubber shoeillustrated in the accompanying drawing.

For the purpose of illustrating'the invention, one preferred formthereof is illustrated in the drawing, this form having been found togive satisfactory and reliable results, although it is to be understoodthat the various instrumentalities of which the invention consists canbe variously arranged and organized, and the invention is not limited tothe precise arrangement and organization of these instrumentalities asherein shown and described except as required by the scope of theappended claims.

Of the drawing:

Figure 1 represents an elevation of a rubber shoe embodying theprinciples of the present invention.

Figure 2 represents a vertical section of the fore part on line 2, 2,011Fig. 1.

Figure 3 represents a vertical section on line 3, 3, on Fig. 1.

Figure 4 represents a plan of the member for uniting the fore part andheel part of the shoe.

Figure 5 represents a section on line 5, 5, on Fig. 1.

Figure 6 represents a similar section of a modification, and

Figure 7 represents a section on line 2, 2 on Fig. 1, and showing amodification of the structure shown in Fig. 2.

Similar characters indicate like parts throughout the several figures ofthe drawing.

In the drawing, i0 is the fore part of a rubber shoe, the heel part I lof said shoe being separated from the fore part by a gap i2, said partsin, II being of non-stretchable rubber such as is usually employed inthe manufacture of rubber shoes.

This gap 12 between the two parts W, H of the shoe is covered by a sheeti3 of elastic rubber which unites the two parts IB, H, at the same timepermitting limited end movement of. the two parts relatively to eachother, so that the rubber shoe may be made to fit various lengths ofleather shoes on which the rubber shoe is to be worn.

The sheet l3 may be in the form shown in full lines in Fig. 4, thecentral part M thereof extending under the instep where it will never besub- J'ected to wear by the surface on which the wearer may betravelling.

Sometimes in purchasing the same size of 5 leather shoes of differentmakes the lengths will vary but with the rubber shoe herein shown anddescribed such rubber shoe may be stretched to fit various lengths ofleather shoes.

Furthermore, it sometimes becomes necessary for a person to commencewearing a slightly longer leather shoe or one in which the sole islonger, and in such a case the rubber shoe. does not need to bediscarded but may be adapted for use on the longer shoe.

-Moreover, where different persons in a home wear leather shoes ofdifferent lengths, the same rubber shoes may be used by any one of thesepersons.

The sheet i3 is vulcanized to the outer surfaces of the sides and solesof the fore part If! and heel part II and its outer surface is made toconform to the outer surface of both fore part and heel part in colorand finish.

If desired, the sheet I3 may have at each end 5 an extension i5 as shownin dotted lines in Fig. 4, and these extensions may be passed over theupper edges it of fore part if! and heel part II and secured to theinner surfaces of the sides and soles of .these parts, as indicated atIT in Fig. 3.

Sometimes the width of the fore part IU of leather shoes will vary inwidth and in order to accommodate the rubber shoe to these variouswidths an elongated gash i8 is cut through and lengthwise of the sidewalls i9 of the fore part It] and substantially parallel to the sidesthereof, and these gashes l8 are covered with sheets 28 of stretchablerubber whichare vulcanized to the outer surfaces of the walls IS! withthe outer surface of said sheet conforming in color and finish to theouter surface of the body portion of said fore part.

The sheet 20 may be applied to the outer surface only, as shown in Fig.2, or if desired additional sheets 2| may be secured to the inner facesof the side walls i9 and secured thereto, as shown in Fig. '7, therebycovering the gash or opening [8.

By the construction of rubber shoe herein shown and described saidrubber shoe may be 50 extended to fit various lengths of leather shoeswhich is obviously a great advantage.

Another advantage is that owing to the elasticity of the sheet 13 thepart 22 of the heel part may be more readily drawn over the heel of theleather shoe, and when once on, the pull of the elastic sheet [3 willcause the part 22 to grip firmly on the heel of the leather shoe andprevent it from becoming displaced accidentally.

It is believed that the many advantages of a rubber shoe so constructedas to fit various lengths and widths of shoes will be fully apparent andrequire no further description.

Having thus described my invention, I claim:

1. A watertight rubber overshoe in which the fore part and heel part aredistinct units of nonstretchable rubber separated at the instep by anarrow gap and connected together by an im-' pervious stretchableelastic rubber sheet having an unbroken plane surface whereby said unitsare movable endwise relatively to each other by the stretching of saidrubber sheet.

2. A rubber overshoe having an elongated narrow opening extendinglengthwise of a side wall of the fore part upper and substantiallyparallel to the sole thereof and a sheet of impervious stretchableelastic rubber material covering said opening and hermetically securedto the outer surface of said side wall.

3. A rubber overshoe having an elongated narrow opening extendinglengthwise of a side wall of the fore part upper and substantiallyparallel to the sole thereof and. sheets of impervious stretchablerubber material covering said opening and hermetically secured toopposite faces of said side Wall.

4. As a new article of manufacture a watertight overshoe, the fore partof which is made of non stretchable rubber with an opening thereinadjacent the sole and is provided with impervious elastic means oversaid opening to permit the widening of the forepart immediately abovethe sole thereof in order to fit various widths of leather shoes overwhich it may be worn.
